Is there an example of populating a tabular form by selecting node in tree

Hi, I am using apex 4.1. I have created a tree region, and would like to click on a child node and have it populate a tabular form. My tree attribute has the following query:
select case when connect_by_isleaf = 1 then 0
when level = 1 then 1
else -1
end as status,
level,
"NODE_LABEL" as title,
null as icon,
"SEQ_NBR" as value,
null as tooltip,
'f?p=&APP_ID.:900:'||:APP_SESSION||'::::P900_SELECTED_NODE:'||"SPECIES_QC_ID" as link
from "#OWNER#"."SPECIES_TREE"
where partner_id = :G_ISSUING_AGENCY and nvl("SPECIES_TREE"."DISPLAY_FLAG",'Y') <> 'N'
start with "NODE_PARENT" is null
connect by prior "SEQ_NBR" = "PID"
order siblings by "NODE_PARENT"
I am not certain how to set up the tabular form....are there any examples out there? thanks! Karen

Thanks Tony,
The application I have is a means of commercial seafood dealers recording what species they have purchased/landed. The page is designed with a tree listing all of the species and their sizes and then the tabular report of landings. The current application uses a collection to display the landings....I was trying to get rid of the collection and populate the table directly.
thanks for getting back to me. Sounds like I will need to keep the collection....just looking for examples.

Apex 3.2 Tabular form - dynamic selection based on prev selection

Hi guys,
I am using apex 3.2. I am having difficulty in setting up a tabular form which provides an option to record information in other columns based on a value selected in the drop down.Here is an example
I have a table product. All the products are added using a tabular form by selecting type from a drop down list.
This allows the user to add multiple products without having to press save each time.
e.g.
product | type
monopoly | game
vase | home
coffee | food
cards | game
Depending on the product type, I want the user to be able to multi-select other options using checkboxes based on the option selected.
So for example if they add a product of type food, it should give additional options like beverage, cereal etc. If they select game, then they should get other options like for age_groups 10-12; 12-16; 18 and over;
Is it posisble to do this on a tabular form in apex 3.2?
If yes, please can someone help.
Thanks
Sam

Tabular form, dynamic select list

Hi,
Direction as to how to tackle this problem politely requested please:
I have a "choices" table of three columns. Sample data shown below:
col1 col2 col3
a b c
a b d
a b e
f g h
f g i
The plan is to show these "choices" as a tabular form. With the example data shown above, this
would be shown as a two row grid, with the first row showing "a b" and at the end of the row there
would be a select box showing four possibilities: "c", "d", "e" or blank.
The "blank" meaning "no choice".
The second row would show "f g" and a select box for "h", "i" or "blank".
Neither the first two columns are editable by the end user - they just get to alter the third column.
How would I go about building this? Would it be a Report with a fancy piece of html for column three,
or perhaps a tabular form?
There can be more than two rows on the screen (of course) - beyond the sample data.
Any directional help appreciated; thanks in advance.

Hi Jure,
On reflection, that mention of the "stragg" function was very useful.
My first reply to you was a little uncharitable, for which I apologise.
Tom Kyte seems to have moved away from the "stragg" function and
has used "sys_connect_by_path" instead.
See http://tkyte.blogspot.com/2007/03/stringing-them-up.html
Once all that is in place (tested out via SQL Developer - not even a mention of Apex) it
seems relatively straightforward to integrate this into an Apex region.
Thanks again.

Tabular Forms and Select Lists

Hi,
I have an updateable tabular form, and one of the updateable columns I want as a select list. I need the SQL that populates this select list to be based on a hidden value in the tabular form. Is this possible?
Cheers
Simon

Hey Simon,
Sounds reasonable, you'll have to end up using the HTMLDB_ITEM.SELECT_LIST_FROM_LOV function within the query that is populating your form.
http://www.acs.ilstu.edu/docs/Oracle/appdev.101/b10992/mvl_api.htm#CHDFGAEC should give you a bit more help towards sorting it out. Don't hesitate to post again if you have anymore queries.

SELECT COUNTRY,COUNTRY_ID FROM CAP_PLAN_COUNTRY_DETAILS'Now, how can I fix this to use the Pole Id every time the country Select List is touched..Can I just modify the query or should I add a Java Script OnChange function to handle this...
Please please help..
Thanks for reading the question...

Isn't this given in my example:
http://apex.oracle.com/pls/otn/f?p=31517:176
The second list is extended by adding:
|| 'WHERE deptno = '
|| c001to make sure it renders correctly once you call your report. In your case the second list would be extended by adding the following
apex_item.select_list_from_query(33, COUNTRY_CODE_ID, 'SELECT COUNTRY,COUNTRY_ID FROM CAP_PLAN_COUNTRY_DETAILS ' || 'WHERE POLE_ID = ' || POLE_CODE_ID
, 'style=""', 'YES', '0', '- Select Country -', 'f33_'
|| LPAD (line_no, 4, '0'), NULL, 'NO' ) COUNTRY_CODE_ID,and that should work.

Tabular form with select list not updating

I have created a tabular form with a dynamic select list
select primary_key, column1,
htmldb_item.select_list_from_query(10,column2, 'select descr d, column_value r from lookup_table where column_value = '||column1) column2
from main_table
The select list appears to work correctly but the new value is not saved to the database. I assume this is because the tabular form element display as field for column2 is set to "standard report column" but when I select any of the "display as text" or "LOV" options either the current data is not displayed or errors are generated.
Any suggestions?
Thanks,
Bob

Hi Ian,
As you have seen, sorting on the project_manager_id column will sort by the id value rather than the textual value. This is, of course, because this is the value in the field.
I haven't tried this out, but one thing that may work is the fact that you don't have to include the ORDER BY fields within the SELECT statement. You could, for example, do:
select p.project_number, p.project_manager_id
from projects p, users u
where p.project_manager_id = u.id (+)
order by u.name
Obviously, you won't be able to do this in the existing statement as you would then be blocked from using column sorting. However, it implies that if you could construct the SQL statement dynamically, appending appropriate ORDER BY strings to the end of the base select statement, you could sort by anything you like. This does, of course, mean that you would have to create a mechanism to allow the user to select the sort order, generate the appropriate string and reconstruct the entire sql statement.
I had had a similar request quite a while ago. The underlying reason for that request turned out to be that the user just wanted to quickly locate records relating to one person. In the end, we agreed that a search filter was the best thing to do.

Andy

Disable columns in a tabular form on select list

I am trying to void out or disable certain columns based on the option value selected from the select list. I have done this on a form with regualr page items. However, I am now trying to accomplish the same on a tabular form. I have tried the following function and onChange event but it doesn't seem to be working. Any idea what could be wrong?
var htmldb_delete_message='"DELETE_CONFIRM_MSG"';
function Disable()
var sel = document.getElementById('f08_0001');
if (sel.options[sel.selectedIndex].value != '5' || sel.options[sel.selectedIndex].value != '7') {
document.getElementById("f04_0000").readOnly = true;
document.getElementById("f05_0000").readOnly = true;
} else {
document.getElementById("f04_0000").readOnly = false;
document.getElementById("f05_0000").readOnly = false;
THe onChange event : onChange="Disable()"

I've even gone ahead and tried th following code but still am having no luck
function Disable(pThis)
var currIndex = $('select[name="'+pThis.name+'"]').index(pThis);
if (pThis.value=='2') {
$('select[name="f04"]')[currIndex].disabled=true;
} else {
$('select[name="f04"]')[currIndex].disabled=false;
}

How to use Ajax Get Multiple Values in Tabular form?

Hi All-
I am trying to use AJAX to get multiple values in tabular form by using Denes Kubicek's example in the following link -
http://apex.oracle.com/pls/otn/f?p=31517:239:9172467565606::NO:::
Basically, I want to use the drop down list to populate rest of the values on the form.
I have created the example(Ajax Get Multiple Values, application 54522) on Oracle site -
http://apex.oracle.com/pls/apex/f?p=4550:1:0:::::
Workspace: iConnect
login: demo
password: demo
I was able to duplicate his example on page 1 (home page).
However, I want to use system generate tabular form to finish this example, and was not able to populate the data correctly.
Page 2 (method 2) is the one that I am having trouble to populate the column values. When I checked application item values in Session, and the values seems to be populated correctly.
This is what I have done on this page:
1. Create an Application Process On Demand - Set_Multi_Items_Tabular2:
DECLARE
v_subject my_book_store.subject%TYPE;
v_price my_book_store.price%TYPE;
v_author my_book_store.author%TYPE;
v_qty NUMBER;
CURSOR cur_c
IS
SELECT subject, price, author, 1 qty
FROM my_book_store
WHERE book_id = :temporary_application_item2;
BEGIN
FOR c IN cur_c
LOOP
v_subject := c.subject;
v_price := c.price;
v_author := c.author;
v_qty := c.qty;
END LOOP;
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn ('<body>');
HTP.prn ('<desc>this xml genericly sets multiple items</desc>');
HTP.prn ('<item id="f04_' || :t_rownum || '">' || v_subject || '</item>');
HTP.prn ('<item id="f05_' || :t_rownum || '">' || v_price || '</item>');
HTP.prn ('<item id="f06_' || :t_rownum || '">' || v_author || '</item>');
HTP.prn ('<item id="f07_' || :t_rownum || '">' || v_qty || '</item>');
HTP.prn ('</body>');
END;
2. Create two application items - TEMPORARY_APPLICATION_ITEM2, T_ROWNUM2
3. Put the following in the Page Header:
<script language="JavaScript" type="text/javascript">
function f_set_multi_items_tabular2(pValue, pRow){
    var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=Set_Multi_Items_Tabular2',0);
if(pValue){
get.add('TEMPORARY_APPLICATION_ITEM2',pValue)
get.add('T_ROWNUM2',pRow)
}else{
get.add('TEMPORARY_APPLICATION_ITEM2','null')
    gReturn = get.get('XML');
    if(gReturn){
        var l_Count = gReturn.getElementsByTagName("item").length;
        for(var i = 0;i<l_Count;i++){
            var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
            var l_ID = l_Opt_Xml.getAttribute('id');
            var l_El = html_GetElement(l_ID);
            if(l_Opt_Xml.firstChild){
                var l_Value = l_Opt_Xml.firstChild.nodeValue;
            }else{
                var l_Value = '';
            if(l_El){
                if(l_El.tagName == 'INPUT'){
                    l_El.value = l_Value;
                }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
                    l_El.parentNode.innerHTML = l_Value;
                    l_El.parentNode.id = l_ID;
                }else{
                    l_El.innerHTML = l_Value;
    get = null;
</script>
Add the follwing to the end of the above JavaScript:
<script language="JavaScript" type="text/javascript">
function setLOV(filter, list2)
var s = filter.id;
var item = s.substring(3,8);
var field2 = list2 + item;
f_set_multi_items_tabular2(filter, field2);
4. Tabular form query:
select
"BOOK_ID",
"BOOK",
"SUBJECT",
"PRICE",
"AUTHOR",
"QTY",
"BOOK_ID" BOOK_ID_DISPLAY
from "#OWNER#"."MY_BOOK_STORE"
5. In Book_ID_DISPLAY column attribute:
Add the following code to element attributes: onchange="javascript:f_set_multi_items_tabular2(this.value,'#ROWNUM#');"
Changed to -> onchange="javascript:setLOV(this,'f03');"
Now, T_ROWNUM2 returns value as f03_0001. But, TEMPORARY_APPLICATION_ITEM2 returns as [object HTMLSelectElement]...
Please help me to see how I can populate the data with this tabular form format. Thanks a lot in advanced!!!

Updated code in Red..

Lets start with looking at what the javascript code is doing.
function f_set_multi_items_tabular(pValue, pRow){
/*This will initiate the url for the demand process to run*/
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
                          'APPLICATION_PROCESS=Set_Multi_Items_Tabular',0);
if(pValue){
    /*If there is an value than submit item name with value*/
    get.add('TEMPORARY_APPLICATION_ITEM',pValue)
    get.add('T_ROWNUM',pRow)
}else{
    /*Else set the item TEMPORARY_APPLICATION_ITEM to null*/
    get.add('TEMPORARY_APPLICATION_ITEM','null')
/*Submit the url and te returned document is of type XML*/
gReturn = get.get('XML');
if(gReturn){
    /*There is something returned*/
    var l_Count = gReturn.getElementsByTagName("item").length;
    /*For all elements of the tag item*/
    for(var i = 0;i<l_Count;i++){
      /*Get the item out of the XML*/
      var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
      /*Get the id of the item*/
      var l_ID = l_Opt_Xml.getAttribute('id');
      /*Get the element in the original page with the same id as
      **the item we have in the XML produced by the ondemand process
      var l_El = html_GetElement(l_ID);
      /*Now get the value of the item form the XML*/
      if(l_Opt_Xml.firstChild){
        var l_Value = l_Opt_Xml.firstChild.nodeValue;
      }else{
        /*There is no value*/
        var l_Value = '';
      if(l_El){
        /*There is an element with the same id as the item we are processing*/
        if(l_El.tagName == 'INPUT'){
          /*The element is an input item just set the value*/
          l_El.value = l_Value;
        }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
          /*If it is a span elment and has the class grabber
          **Then set the innerHTML of the parent to the value
          **and the id of the parent to the id
          l_El.parentNode.innerHTML = l_Value;
          l_El.parentNode.id = l_ID;
        }else{
          /*Else set the value as innerHTML*/
          l_El.innerHTML = l_Value;
get = null;
Now where it went wrong in your initial post
The XML that was returned by your XML process would be something like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_1">CSS Mastery</item>
<item id="f03_1">22</item>
<item id="f04_1">Andy Budd</item>
<item id="f05_1">1</item>
</body>
When you don't use apex_item to create your tabular form a item in the table will look like
<input id="f02_0001" type="text" value="CSS Mastery" maxlength="2000" size="16" name="f05" autocomplete="off">
Notice the id's f02_1 and f02_0001 don't match.
So to make it work the XML would have to look like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_0001">CSS Mastery</item>
<item id="f03_0001">22</item>
<item id="f04_0001">Andy Budd</item>
<item id="f05_0001">1</item>
</body>
To do that simply use lpad in the ondemand process like
HTP.prn ('<item id="f02_' || lpad(:t_rownum,4,'0') || '">' || v_subject || '</item>');
HTP.prn ('<item id="f03_' || lpad(:t_rownum,4,'0') || '">' || v_price || '</item>');
HTP.prn ('<item id="f04_' || lpad(:t_rownum,4,'0') || '">' || v_author || '</item>');
HTP.prn ('<item id="f05_' || lpad(:t_rownum,4,'0') || '">' || v_qty || '</item>');
Keep in mind that the above is based on your original post and #ROWNUM# not being lpadded with zero's.

Manual tabular form -- add rows

Hi everybody, I am making a manually tabular form following the Denes Kubicek tutorials:
http://apex.oracle.com/pls/otn/f?p=31517:170:1304244099066416::NO
and
http://apex.oracle.com/pls/otn/f?p=31517:190:1304244099066416::NO
The SQL for the tabular form is:
SELECT apex_item.checkbox (31,
idint,
'onclick="highlight_row(this,' || ROWNUM || ')"',
NULL,
'f31_' || LPAD (ROWNUM, 4, '0')
) delete_checkbox,
idint,
apex_item.text (32,
tipus_modif,
1,
1,
'style="width:20px" ',
'f32_' || LPAD (ROWNUM, 4, '0')
) tipus
FROM GPPC_DETALLS_ESMENA_PROP_V
where esmena_idint = :P18_IDINT
and tipus_modif ='A'
The Report is created correct. Now I modify the "Form Region" template like this:
<table class="t6FormRegion" id="MY_TAB" border="0" cellpadding="0" #REGION_ATTRIBUTES# summary="">
<tr><td class="t6Header">#TITLE#</td></tr>
<tr><td class="t6ButtonHolder">#CLOSE# #PREVIOUS##NEXT##DELETE##EDIT##CHANGE##CREATE##CREATE2##EXPAND##COPY##HELP#</td></tr>
<tr><td class="t6Body">#BODY#</td></tr>
<tr><td><img src="#IMAGE_PREFIX#themes/theme_6/t.gif" width="400" height="1" alt="" /></td></tr>
</table>
Now I add a Button URL with the code:
javascript:va_AddTableRow(this,'MY_TAB',1);
and add this Javascript in the region header of the SQL Report
<script>
function va_AddTableRow(pThis,pThat,pNum){
var tt = html_GetElement(pThat);
for(i=0;i<pNum;i++){
var ogTR = tt.rows[1];
var trClone = ogTR.cloneNode(true);
trClone.firstChild.innerHTML='(null)';
var last_child=trClone.lastChild.getElementsByTagName('input')
for (var j=0;j<last_child.length;j++)
if (last_child[j].type=="hidden" && last_child[j].name=="f01")
last_child[j].value="";
if(document.all){
myNewRow = tt.insertRow(tt.rows.length);
oReplace = myNewRow.replaceNode(trClone);
}else{
tt.appendChild(trClone);
</script>
In this moment, when I push the botton appears the text (nulll) in the same region but not as a new line in the SQL report, what is the problem??
Thank you for your help

Alberto,
When you get a chance, see if maybe this (old version) of my app does something similar to what you need/want.
[http://apex.oracle.com/pls/otn/f?p=26115:3]
It's not working right now though, I keep getting the Oracle error:
ORA-01116: error in opening database file 17252 ORA-01110: data file 17252: '/u03/oradata/marvlprd/MARVLPRD/datafile/o1_mf_flow_172_23qtsjpr_.dbf' ORA-27041: unable to open file Linux Error: 23: Too many open files in system Additional information: 3
So, as way of an explanation (until Joel gets the Linux process fixed), I have a simple little screen that I use for letting the users specifiy search criteria. Each line has four columns, what field they want to search, a condition (equals or not equals), the text to search for, and an optional 'And/or' argument. If the 'And/Or' gets populated, a new blank line automatically gets created. There is also a red 'X' on each line so they users can delete a line if they want.
Not sure if this is what you need, but this page uses the same set of javascript code, so perhaps when it's working again, you can see if there are any similarities or differences.
Also, for reference, so you can see the code and variables, etc., the workspace is wbfergus, and the id and password are both htmldb-apex.

Interactive report limits tabular form pagination.

Hey All,
I am running into a problem and I was unable to find an answer on the forum, however I did find that someone asked the same question but did not get any replies. So I will ask it again.
Pagination problem with interactive report and multi row update form
I created a page which contains both an IR and a tabular form. The IR behaves correctly and there are no issues. The tabular form on the other hand is not functioning properly. The problem I am having is that the tabular form will only paginate to the rows that are currently being displayed in the IR. For instance if I am viewing rows 6-10 on the interactive report the tabular form will start from row 6 even if my pagination scheme is set to view in increments of 20.
Another example is if the IR is is viewing rows 6-10 and the tabular form is viewing rows 1-2. If I paginate on the tabular form it will jump to rows 6-7 regardless of where its last position was.
So in short it appears that my tabular form always starts from the first row currently being viewed in the IR. Is there a work around for this or should I just ditch the interactive report?

Munky,
Thanks for the suggestion. It does indeed allow me to paginate but I hate the alert you get when PPR is enabled for a tabular form and unfortunately so do the users. :(
Cheers,

HTMLDB 2.0 bug - tabular forms - select list from named LOV

Hi!
Changing a column in a tabular form to 'select list (named lov)' gets the following error in HTMLDB 2.0 when you try to add a row (to an empty table in my case):
PL/SQL error at column 133.
Create a table and then create a tabular form on it. Then change a report column to be a 'select list (named lov)'. Save and run the form and the error occurs.
Thanks!

Detect changes on tabular form

HI guys!
Is there any way to detect that there were some changes made on tabular form? My Client wants me to create items which are conditional upon changes made on tabular form. IE button X is only visible if there were no changes made on tabular form.
With regards,
PsmakR

Hello Konrad,
>> Stronger should be hiding button because there are changed cells …
OK. This is the simpler scenario.
The button should be rendered upon loading the page, as at this point there are no changes to the form.
You should leave the checkbox column, which selects your rows, unchanged (event free), as it doesn’t affect the visibility status of the button – it should remain visible even if rows were selected (without changing any other cells).
As I suggested in my first post, you should use the onchange event with all the other editable columns. The event should call a JavaScript function that hides the button, because when fired it means something has changed in one of the cells.
Regards,
Arie.

Retrieving tabular forms

Hi,
I want to display a tabular from for multiple records.I can display it using data block winzard and cursor fetch method.
But now I want to dislay different attributes in 1 tabular column.When I set the data block winzard,I assign 1 attribute
to 1 text_item.But I dont't know how to assign multiple table columns(attributes)into 1 tabular text_item.
Can anyone tell me how to do that??
Thanks.

Tyler,
I think you are right. I also share your opinion in the most of the details except those related to cancer and ugly :). But what I also know is that the most of my customer wouln't consider using apex if there would be no feature like tabular forms. At least the half of the projects I did so far were replacements of some internal applications running in access or even excel and without a possibility to emulate tabular updates apex simply wouldn't have a chance. ;) And if you take more than just a few days away from the forum and come back once the version 4 is there, you will probably notice that there is even more of that stuff arround:
- websheets
- updatable interactive reports
- enhanced support of tabular forms
I am convinced this is the right way to go - those popular feature needs to be enhanced. This way apex is going to gain even more popularity and eventually completelly replace Access.

Select List having 2 items ... Add Text(return value 1) and No Text(return value 2)
if value =1 then i want to enable text box , so user can enter value.
if value=2 then text box won't allow to add text or will become disalbe.
Please Help

Hi,
You can do this by using a small java script
<script language="JavaScript" type="text/javascript">

</script>Here P2_Text is the text box whose value I am enabling or disabling based on the selected value from a List box. On The list box I have onChange="javascript:FldEnableDisable(this.value)" ( You can specify this under HTML Form Element Attributes)
Thanks,
